BMW I4 vs Polestar 3

What's the difference?

If you’re intimidated by the electric future, don't be, because BMW’s i4 is just as good as any non-M sedan BMW offers right now.

The i4 delivers all the things you love about a 3 Series, engaging driving dynamics, a well-appointed interior and comfortable ride, but its all-electric powertrain means you’ll never have to stop at a servo again.

With a large battery on board, the i4 also serves up a decent driving range that should put anxiety-prone EV drivers at ease.

That is, of course, if you can get onboard with the looks.

The Polestar 3 Long Range Dual Motor with Performance Pack offers a lot of good stuff and in a segment filled with jellybean-on-wheels-designs, it looks great!

It’s large and comfortable enough for a family but the technology feels overworked and that hurts its functionality for me. So much so that at times it feels like you were driving a phone, rather than a car.

If the i4 looks familiar, that’s because it is based on the 4 Series Gran Coupe that entered showrooms last year.

This means a four-door liftback body style with a sloping roofline, athletic proportions and sizing close to the Tesla Model 3 and Polestar 2.

Let’s get it out of the way early and talk about the elephant in the room, the oversized front grille.

Say whatever you want about it, there’s no denying it gives the i4 a unique and head-turning look, and in my opinion, it’s not too bad.

In the flesh, it really isn’t as big as the press photos have made it out to be, and with the front numberplate to split it up, it does start to look a bit more like a traditional grille.

In profile, the 19-inch wheels fill out the arches well, and hide the massive brakes that add to the i4’s sporty appearance.

I particularly like the almost flush door handles that look futuristic, but aren’t as pretentious as those retractable handles you see on Teslas and Range Rovers.

Slim tail-lights and a chunky bumper inform the styling of the i4’s rear, but we’re really not a fan of a rear diffuser that keeps the exhaust cut-outs.

It makes sense on a model like the 4 Series Gran Coupe, but it just looks look rather odd on an all-electric model like the i4.

While the outside of the i4 might be all about that big grille, the inside is all about big screens, two of them in fact.

The instrumentation and multimedia screens dominate the experience inside, but BMW has also included physical buttons on the steering wheel and centre stack, as well as a rotary control knob, to make navigating the menus that much easier.

The connected screens differentiate the i4 from its 4 Series Gran Coupe relative, and make the cabin feel futuristic and befitting of the all-electric powertrain.

Overall, the i4’s styling might not be to everyone’s tastes, but BMW definitely gets credit for being bold in its aesthetic choices.

Would have been nice to see BMW’s designers go a bit further in differentiating the i4 from its 4 Series Gran Coupe cousin, but there's no denying the head-turning appeal of this all-electric sedan.

Where the Polestar 2 is mid-size, the Polestar 3 looks enormous but both feature what I like to refer to as Polestar minimalism. Crisp lines showcase the body without ever looking flashy.

There’s a distinct, growly edge to the Polestar 3 which its rivals lack with their pillowy designs and there’s no other word for it - it's hot.

While the thoughtfully sourced Nappa leather is a nice touch, it feels like virtue signalling to have the fact stencilled on the seats themselves. I don't need to know that it used 8.1kg of CO2e per square metre of material to produce, but it might float your boat.

This supple material is set against some lovely soft-touch knit fabrics that look great but easily pick up marks.

The Swedish Gold accents in the seatbelts and ambient lighting add some personality but the cabin looks too similar to its far more affordable sedan cousin for its price point.

The simply-styled but high-end looking interior won’t appeal to all, especially not when you’re considering the cabins of its flashier rivals but there is something beautiful in its minimalism.

As a premium mid-sized sedan, the BMW i4 offers up enough storage and space for most, but keep in mind there are limitations.

From the driver’s seat, everything is well placed and the electronically adjustable seats offer plenty of adjustability to get comfy for long road trips.

Storage options include an central cubby, glove box, two cupholders and small door pockets that just about fit a bottle, but the design means it rattles around a little.

Speaking of fiddly, between this car, and the weird plastic cowl thing found in the Z4 and 1 Series, BMW needs to be called out for some of the most annoying wireless smartphone charger designs.

This one is tucked all the way under a retractable lid, and is barely wide enough to fit some flagship-sized phones.

However, we will give BMW huge props for its iDrive8 multimedia system, which is displayed on a huge 14.9-inch screen.

The menus are clear, concise and intuitive, while the software is buttery smooth and responsive. It feels snappier than some phones we’ve used in the past.

Credit too for not making all inputs touch, as there is a rotary control knob and voice command capability available.

In the second row, things are a little more cramped, but at 183cm tall I can fit in the outboard seats with tight headroom.

There’s enough leg and shoulder-room, too, and passengers can make use of the climate controls, USB-C charging ports and a fold-down-centre armrest with two cupholders.

Opening the boot reveals 470 litres of volume, but fold the rear seats down and that pace swells to 1290L.

Loading large and bulky items is made much easier thanks to the liftback design, and it’s important to note i4 buyers aren't penalised in terms of practicality as the i4 and 4 Series Gran Coupe share the same boot capacity.

However, the charging cables can get in the way, as there isn’t any dedicated space for them.

The charging point is also in an annoying spot, in the right-rear fender where the petrol cap would be.

It means that you always have to reverse into charging spots, and it can be tricky to manoeuvre the i4 into just the right position to get the charging cable to reach.

The Nissan Leaf's front centre charging port, or the dual charging ports available on the left and right fenders in the Audi e-tron or Porsche Taycan are preferable.

The best part of the Polestar 3 cabin is the space available for all occupants! What it lacks in a third row, it more than makes up for in legroom. So, if you have a couple of lanky teenagers in tow, they'll be happy.

Passenger access is excellent via the wide door apertures and 202mm ground clearance. The front seats offer the most comfort with their heat, ventilation and five-mode massage functions. However, the rear seats are ergonomic and well-padded, so even back there, you won't get fatigue on a longer journey.

Storage isn't as clever as it could be but you still get some solid options. There's a glove box (opened via the touchscreen) that can fit a manual; a middle console, under-shelf cubby that has an elastic tech pouch and a centre console that features two cupholders and a phone cradle.

In the rear you get small storage bins in each door, two cupholders in a fold-down centre armrest and two map pockets.

Other amenities in the rear are okay but not class-leading, especially not for a top-grade model. Back rowers get climate control, heated outboard seats, two USB-C ports and reading lights but that's about it. A few practical items like sun blinds and extra storage options would be good for a family SUV at this price point.

The boot offers a maximum of 597L of storage capacity available when all five seats are in use but that can be bumped up to 1411L when the rear row is folded. The rear row has a 60/40 split with a ski-port door that adds variation to the configuration.

A level loading space makes it an easy car to slide gear in and out of. The floor folds up to reveal a large storage pocket underneath which is a handy spot for when you only have a few items and don’t want them rolling around.

Like most EVs you don’t get a spare tyre, just a tyre repair kit but you do get a powered tailgate with kick function.

Now we come to what has become the least practical aspect of the cabin for my family and that's the technology.

There's no denying the 14.5-inch portrait-style multimedia touchscreen looks awesome. And when it works, it's great. But the emphasis is on 'when it works'.

If you’re familiar with the Volvo systems, you’ll figure it out, but if you’re not - expect to spend some quality one-on-one time with the system because this isn't a simple ‘get in and go’ set up. 

It's run by Android Automotive which means you get a whole bunch of Google apps built-in, like Maps, Assistant and Google Play. There are others, like YouTube, Spotify and Tidal as well. A software update later in the year should see Apple CarPlay enabled.

The system seems to have a few gremlins and there are sporadic moments where the touchscreen functionality stops, or menus/functions can't be accessed. As when the key fob battery was low and the wireless charging pad could not be enabled. A full reset on the system was required to restore functionality.

Outside of volume control, everything is accessed via the screen and that means you're one glitch away from not being able to use the vehicle optimally or open your glove box.

The 25-speaker Bowers & Wilkins surround sound system with Dolby Atmos is nice, though.

There are two variants available for the Polestar 3 Long Range, a Single Motor and a Dual Motor, but a few different packs can be added to the chosen variant to further personalise it.

We're in the top-grade Dual Motor with Performance Pack; a pack that adds $11,700 to the 'base' Dual Motor variant and brings its price tag to $144,420 MSRP.

The Performance Pack adds 'Swedish Gold' accents on the seatbelts, ambient lighting system, tyre valves and calipers. There are Brembo brakes behind the 22-inch performance wheels and the chassis has been tuned for performance.

Standard kit for this model includes adaptive air suspension, adaptive LED headlights and LED tail-lights, keyless start/entry and three-zone climate control. The Android Automotive system runs a few different built-in Google apps like Google Assistant, Maps and YouTube. An update later in the year should see Apple CarPlay become integrated.

Other equipment includes a panoramic sunroof, 14.5-inch multimedia touchscreen, 360-degree view camera system, a powered tailgate, at home charging cable and electric front seats with heat function and extendable under-thigh supports.

Now come the little extras.

Our test model has the $2000 optional black 'Space' paintwork and 'Plus Pack' which adds $9000 and includes a head-up display, a 25-speaker Bowers & Wilkins audio system, active noise cancelling tech, a foldable boot floor, heated steering wheel and rear outboard seats, power-operated steering column, air quality filtering for the air-conditioning system and soft close doors.

There is also an upgraded Nappa pack for $7500 which adds animal welfare secured (which almost feels like a misnomer) Nappa leather upholstery from Bridge of Weir, black ash deco panels and front seats with five massage modes, powered side support and ventilation function.

The top-model grade more than holds its own in terms of motor outputs compared to its rivals the BMW iX xDrive 50 Sport and Mercedes-Benz EQE 500 SUV, but the BMW has it beat with a longer driving range.

And despite technicality sitting as the most affordable with its base price, the extra packs our test model has put it at over $180K drive-away and, well, that feeling of value starts to slide for me.

If there’s one thing BMW knows how to do well, it’s building a sports sedan like no other. And that holds true for its EVs.

Powering this i4 eDrive40 is a single electric motor that produces 250kW/430Nm, which beats the outputs of even the 330i and 430i Gran Coupe.

With drive sent to the rear wheels, the i4 eDrive40 can accelerate from 0-100km/h in just 5.7 seconds, beating out the aforementioned 330i and 430i models.

For those that want a bit more pep, the top-spec M50 grade’s dual-motor set-up punches out 400kW/795Nm for a lightning quick 3.9s 0-100km/h run.

Compared with its petrol-powered 4 Series Gran Coupe counterpart, the i4 certainly puts up respectable figures, while offering more than a performance match for the Polestar 2 and Tesla Model 3.

Our test model is a dual motor all-wheel-drive, with two 180kW permanent magnetic motors at each end of the vehicle. The Performance Pack adds a software upgrade which boosts the outputs (20kW/70Nm) and together this model produces up to 380kW of power and 910Nm of torque.

This gives you an impressive 0-100km/h sprint time of just 4.7-seconds and a top speed of 210km/h.

The chassis has been tuned with performance in mind and there is torque vectoring on the rear axle, as well as a rear motor disconnect clutch to save power at lower speeds.

Despite its massive outputs, I haven’t felt overwhelmed by the power but it has plenty of it to ensure a quick on-road experience. You certainly don’t feel like you can’t overtake!

With an 84kWh battery the official range on this i4 eDrive40 is pegged at 590km when tested to WLTP standards.

However, when fully charged, our test car's range readout was around 390km.

But keep in mind EVs aren’t as effective in cold weather, and the mercury was showing only three degrees on most days during this freezing Irish winter.

Luckily then, BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

Using an 11kW AC charger however, will require 8.5 hours for a full charge.

In a week with the car, I averaged an energy consumption rating of 23.4kWh per 100km, almost matching the official figure of 22.2kWh/100km.

My driving included several long-distance trips on the freeway, however, an environment in which an electric vehicle does not excel.

Worth noting the heavier and more energy-hungry M50’s official driving range drops to 510km, but we’re yet to test its real-world figures.

The Long Range Dual Motor with Performance Pack has a lithium ion battery with a large 111kWh of capacity but its claimed WLTP driving range is only up to 567km which positions it in the middle of its rivals.

This isn’t a bad driving range but I’d want an even longer one for a family SUV because it means less time at the charging stations with your kids on a road trip.

The Polestar 3 has a Type 2 CCS charging port and it can be connected to a rapid DC charger. It can accept up to 250kW on this type of system, which is excellent.

An 11kW AC or 50kW DC charger will take up to 11 hours or two and a half hours to charge, respectively.

Our test model has an official claimed WLTP energy consumption range between 21.9 to 23kWh/100km and after a mix of open and city driving we managed to hit an average of 20.4kWh, which is good for such a big EV.

If you came here just to find out whether BMW has succeeded in transplanting its signature sports sedan characteristics into the all-electric i4, the answer is, yes.

The best thing I can say about the i4 is that, aside from the way power is delivered and the lack of engine and exhaust noise, it feels just like a 3 or a 4 Series.

Steering is sharp and responsive, throttle and brake inputs are immediate, making this rear-drive i4 a delight to drive enthusiastically.

The staggered Michelin Pilot Sport 4 tyres and massive brakes obviously help in this regard, and look, it’s not as sharp as the Porsche Taycan, still the sharpest electric vehicle we’ve driven to date, but the driving experience in this i4 is comparable to the excellent 3 Series.

But I’m not in love with the fake sound piped into the cabin when in 'Sport' mode. It sounds weirdly low-rent and I much prefer to accelerate to triple digit speeds in serene, near-silence.

Switch things up to 'Comfort' mode, and the i4 makes for a surprisingly relaxed drive.

The steering gets bit a looser and the adaptive dampers ease off a little, soaking up bumps and road imperfections with minimal affect to occupants.

Pair this with the nearly-silent electric powertrain, and well, our little one in the back seat has fallen asleep on more than one occasion in my time with the car

You can also adjust the level of regenerative braking in the i4 and operate it with one pedal like in the Nissan Leaf and Hyundai Ioniq 5.

This is a more efficient way to drive an EV as it forces you to look ahead and be careful with your throttle inputs.

One-pedal driving might not be for everyone, but it’s nice to have the option there.

I have been a little surprised by the top-model grade this week. It’s got heaps of power and your tummy does a little leap when you really have to put your foot down but the strong regen braking and adjustable one-pedal function (up to two levels) take a long time to get used to and sometimes it just feels like it's champing at the bit but not in a fun, sports car way.

The Polestar 3 sits lower to the ground than some other large SUVs but it’s not as steady as I would expect in cornering. The adaptive suspension is adjustable depending on the drive mode you select but remains fairly firm and you feel the bigger bumps.

The visibility is great and none of the pillars are in the way from my driving position, the frameless side mirrors also add a wide view into your blind spots. 

The active noise cancelling tech means the cabin is delightfully quiet and it's very easy to chat with the back seat passengers. I’ve hated that you can’t ‘close’ the sunroof though because despite there being little to no heat, the constant sunlight is really annoying.

The 360-degree view camera system is high quality and despite a few fish-eye lens angles you can get, this is a very easy SUV to park.

My dad struggled with the concept of not turning the car on or off, and in his words "it just feels wrong!". This is a Polestar experience though that you get used to (eventually).

However, the aspect I struggled with is that you get two 'keys' - an easily lost key fob and a keycard (same size as a credit card).

You apparently need both to access the vehicle - the keycard to unlock/open the doors if the key fob proximity feature doesn't register and the key fob to actually drive.

Although, at a pinch the keycard is technically a second key and can be used to drive if the battery on the key fob runs out. Oh, did I mention you have to charge the key fob? It all seems a bit superfluous.

The Polestar 3 hasn't been assessed by ANCAP yet, so is unrated, but there's not much it doesn’t have when it comes to its safety equipment and it features nine airbags which is great for a family SUV.

The standard safety kit includes adaptive cruise control, blind-spot monitoring, driver monitoring, lane departure warning, lane keeping aid, parking assist, traffic sign recognition, 360-degree camera system, front and rear parking sensors, rear cross-traffic alert, tyre pressure monitoring and occupant detection alert.

Some highlight features include an alarm system with interior motion sensors, automatic unlocking in a collision, emergency e-call, and Volvo's 'Whiplash Injury Protection System' consisting of energy absorbing backrests and specially designed head restraints in the front seats.

The adaptive cruise control is great but has one too many steps to get it going.

The Polestar 3 has forward and rear collision warning, as well as AEB with cyclist, pedestrian and car detection.

There are two ISOFIX child seat mounts and three top tether anchor points on the rear seats but two seats will fit best.

Like all BMWs sold in Australia, the i4 comes with a three-year/unlimited kilometre warranty with roadside assist over that period.

This falls short of the now-standard five-year assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus and Mercedes-Benz.

Scheduled servicing intervals for the i4 are every 20,000km/24 months, at least in overseas materials.

Australian intervals are yet to be confirmed, but BMW is offering service price plans covering four- and six-year periods in 'Basic' and 'Plus' forms.

The Basic plan for four and six years is set at $1240 and $1765 respectively, while the Plus package is $4805 and $5500.

Polestar offers the Polestar 3 with a five-year/unlimited warranty and the battery is covered by an eight-year or up to 160,000km warranty. You also get a free service plan for the first five years or up to 100,000km of ownership, whichever comes first.

Considering its position in the premium-end of the EV market, this is good value compared to its Euro rivals.
